CROSS-REFERENCE TO RELATED APPLICATION

The present disclosure claims the priority to the Chinese patent application with the filing number 202220725644.7, filed on Mar. 29, 2022 with the Chinese Patent Office, and entitled “Pick-up Truck Mattress”, the contents of which are incorporated herein by reference in entirety.

TECHNICAL FIELD

The present disclosure relates to the field of inflatable beds, and in particular, relates to a pick-up truck mattress.

BACKGROUND ART

The inflatable beds utilize the characteristic that air is permeable to enable the human body to be fit with the bed completely when sleeping, and allow various parts of the human body to be uniformly stressed, so that the blood circulation disorder caused by uneven stress of the conventional beds is effectively improved. The air bed is also known as health care bed in the foreign countries. The inflatable beds can be inflated when in use, with an inflation amount being controlled. The inflatable beds can be deflated when not in use, thus reducing the volume, facilitating storage, and being quite flexible to use. The inflatable beds in the prior art are substantially in regular shapes, such as square or circular shape, and cannot be used directly in the pick-up trucks.

At present, when a pick-up truck is used, a mattress can be placed in a cargo compartment of the pick-up truck, and people can rest on the mattress, thus improving the comfort of use. In the prior art, the mattresses are mostly inflatable mattresses each having one air chamber. However, in order to enable the mattress to avoid convex shell portions corresponding to rear wheels in the cargo compartment, the mattress needs to be set relatively thick, thus the stability of the mattress is poor.

In view of this, the designer designs a pick-up truck mattress. By designing the mattress with two air chambers in communication with each other, an air chamber located at the periphery can enhance the strength of edges of a middle air chamber, and the stability is good during use.

Referring to FIG. 1 and FIG. 2 , in the present embodiment, a pick-up truck mattress includes a main air chamber 100 and an annular air chamber 200 in communication with each other, two opposite sides of the main air chamber 100 are each provided with two convex portions 121, and the two convex portions 121 on the same side define therebetween an avoidance groove 122 configured to avoid a wheel (i.e. avoid a portion where the corresponding wheel is located); the annular air chamber 200 is provided around the main air chamber 100, and the annular air chamber 200 is located at one sides of the convex portions 121 in a thickness direction of the main air chamber 100 and shields the avoidance grooves 122.

In the present embodiment, it should be understood that the main air chamber 100 and the annular air chamber 200 are in communication with each other, and thus when an inflation pump is used to perform inflation, a gas can simultaneously or sequentially enter the main air chamber 100 and the annular air chamber 200, so that the main air chamber 100 and the annular air chamber 200 satisfy the use requirements. For example, a flow dividing pipe in communication with the annular air chamber 200 may be provided in the main air chamber 100. The flow dividing pipe is in communication with the main air chamber 100, and the flow dividing pipe is provided therein with a unidirectional valve to allow only the gas in the main air chamber 100 to enter the annular air chamber 200. In the case that the inflation pump is used to inflate the main air chamber 100, when air pressure in the main air chamber 100 reaches a certain value, the unidirectional valve is opened under the action of the air pressure, and then the gas enters the annular air chamber 200 through the flow dividing pipe to inflate the annular air chamber 200.

In addition, the main air chamber 100 and the annular air chamber 200 can be independently provided with an air release valve, so as to independently control the air pressure in the main air chamber 100 and the annular air chamber 200, and further independently control the flexibility.

Referring to FIG. 1 to FIG. 3 , in the present embodiment, optionally, the main air chamber 100 includes a bottom wall 110, a first enclosure 120, a second enclosure 130, and a top wall 140. The convex portions 121 are provided on the first enclosure 120. The bottom wall 110 is connected to a side of the first enclosure 120. The second enclosure 130 is connected to a side of the first enclosure 120 away from the bottom wall 110. The top wall 140 is connected to a side of the second enclosure 130 away from the first enclosure 120. Specifically, the bottom wall 110 and the top wall 140 are substantially “H” shaped pieces. The bottom wall 110 has a first left side edge 111, a first front side edge 113, a first right side edge 112, and a first rear side edge 114 which are connected end to end in sequence. A middle position of the first left side edge 111 and a middle position of the first right side edge 112 are each provided with a first notch. By the same reasoning, the top wall 140 has a second left side edge 141, a second front side edge 143, a second right side edge 142, and a second rear side edge 144 which are connected end to end in sequence. A middle position of the second left side edge 141 and a middle position of the second right side edge 142 are each provided with a second notch. In the above, the left side edges and the right side edges are arranged in a width direction of the main air chamber 100, and the front side edges and the rear side edges are arranged in a length direction of the main air chamber 100. The first enclosure 120 is annular, and the first enclosure 120 has a first annular edge 123 and a second annular edge 124 in the thickness direction of the main air chamber 100. The first annular edge 123 has the same shape as the bottom wall 110. The first annular edge 123 is connected to the bottom wall 110. The second annular edge 124 is connected to the second enclosure 130, and a side of the second enclosure 130 away from the first enclosure 120 has the same shape as the top wall 140 and is connected to the top wall 140. The notches on the first left side edge 111 and the first right side edge 112 on the bottom wall 110 are respectively corresponding to one sides of the two avoidance grooves 122 of the first enclosure 120, with the sides close to the bottom wall 110, and the notches on the second left side edge 141 and the second right side edge 142 on the top wall 140 are respectively corresponding to one sides of the two avoidance grooves 122 on the first enclosure 120, with the sides close to the top wall 140. The second enclosure 130 has a cross-sectional profile that is substantially in an “H” shape, and the second enclosure 130 has a third annular edge and a fourth annular edge 132 arranged in the thickness direction of the main air chamber 100. The second enclosure 130 has a cross-sectional area that decreases gradually in a direction from the third annular edge to the fourth annular edge 132. The third annular edge has the same shape as the second annular edge 124 of the second enclosure 130 and is connected to the second annular edge 124 of the second enclosure 130, and the fourth annular edge 132 has the same shape as the top wall 140 and is connected to the top wall 140. In other words, the fourth annular edge 132 is closer to a central position of the top wall 140 than the third annular edge, and the second enclosure 130 gradually moves towards the central position of the top wall 140 in a direction from the third annular edge to the fourth annular edge 132. In this way, the second enclosure 130 and the first enclosure 120 have an included angle, and the second enclosure 130 forms a cable-stayed structure.

Further, the main air chamber 100 further includes first pull straps 150, and the first pull straps 150 each have one end connected to the top wall 140, and the other end connected to the bottom wall 110, improving the stability of the main air chamber 100.

Optionally, the second enclosure 130 may be provided as an integrated structure, or the second enclosure 130 is formed by connecting a plurality of connecting pieces end to end in sequence. The second annular edge 124 of the first enclosure 120 is connected to the third annular edge of the second enclosure 130, wherein the joint where the two are connected is a first connecting portion whose profile is in an “H” shape. The fourth annular edge 132 of the second enclosure 130 is connected to an outer edge of the top wall 140, wherein the joint where the two are connected is a second connecting portion whose profile is in an “H” shape.

In the present embodiment, optionally, the annular air chamber 200 surrounds the second enclosure 130, and an outer circumferential wall of the annular air chamber 200 does not protrude beyond the convex portions 121 of the second enclosure 130, and further, the outer circumferential wall of the annular air chamber 200 is substantially located in the same plane as an outer side of the convex portions 121 of the second enclosure 130.

Optionally, the annular air chamber 200 includes an annular sheet 210, a third enclosure 220, and a second annular sheet 210. The annular sheet 210 and the second annular sheet 210 are both connected to the third enclosure 220. The annular sheet 210, the third enclosure 220, and the second annular sheet 210 are all provided around the second enclosure 130 and define an annular cavity, together with the second enclosure 130. A side of the annular sheet 210 away from the third enclosure 220 is connected to the second connecting portion, and a side of the second annular sheet 210 away from the third enclosure 220 is connected to the first connecting portion.

Further, the annular sheet 210 includes two first connecting bodies 211 and two first blocking bodies 212. The two first connecting bodies 211 and the two first blocking bodies 212 are arranged alternately and connected end to end; and the two first blocking bodies 212 each protrude beyond the first connecting bodies 211 in a direction from the outside to the inside of the annular air chamber 200. The second annular sheet 210 includes two second connecting bodies 211 and two second blocking bodies 221. The two second connecting bodies 211 and the two second blocking bodies 221 are arranged alternately and connected end to end; and the two second blocking bodies 221 each protrude beyond the second connecting bodies 211 in a direction from the outside to the inside of the annular air chamber 200. The two first blocking bodies 212 and the two second blocking bodies 221 are respectively provided corresponding to and opposite to each other in the thickness direction of the main air chamber 100, and the second blocking bodies 221 are configured to shield one sides of the avoidance grooves 122 close to the top wall 140. That is to say, after the mattress is inflated, positions where the first blocking bodies 212 and the second blocking bodies 221 are located are corresponding to the positions of the avoidance grooves 122, to shield one sides of the avoidance grooves 122 away from the bottom wall 110, so that after the mattress is placed in the cargo compartment of the pick-up truck, portions of the annular air chamber 200 corresponding to the second blocking bodies 221 cover the convex shell portions configured to avoid the rear wheels on the cargo compartment.

Optionally, the annular air chamber 200 further includes second pull straps 230, and the second pull straps 230 are simultaneously connected to the annular sheet 210 and the second annular sheet 210. Specifically, the second pull straps 230 are simultaneously connected with the paired first blocking bodies 212 and the second blocking bodies 221.
